Gel Doc EZ gives analysis results in seconds


Easy imaging without sacrificing quality or accuracy

The Gel Doc EZ imager from life sciences supplier Bio-Rad Laboratories delivers publication-quality images and gel analysis results in seconds — with just the push of a button.

The system is for researchers who perform DNA, RNA, and protein electrophoresis as well as western blotting.

The Gel Doc EZ imager requires no training for first-time users and provides automated push-button functionality. This eliminates the need for researchers to manipulate manually filters, lenses, or lighting, thereby minimising the potential for human error, the company says.

‘With the Gel Doc EZ imaging system, we’ve made imaging easy without sacrificing quality or accuracy,’ said Ryan Short, marketing manager for Imaging Systems at Bio-Rad Laboratories.

The imager allows the use of multiple application-specific trays, including a UV tray for imaging fluorescent stains such as ethidium bromide, a white tray for imaging colorimetric stains such as Coomassie blue, a blue tray for imaging SYBR Green-stained DNA, and a stain-free tray for imaging proteins separated by electrophoresis on Bio-Rad’s Criterion TGX Stain-Free precast gels.

The company claims the Gel Doc EZ imager is the only gel documentation system capable of imaging stain-free gels, an advanced gel technology that condenses traditionally long staining protocols down to a five-minute activation and imaging process.

Researchers performing SDS-PAGE and staining with Coomassie blue can spend more than two hours after electrophoresis to get properly stained protein bands. Most staining protocols include multiple manual stain and wash steps. Stain-free technology eliminates this bottleneck and allows scientists to generate results faster, the company says.

The Gel Doc EZ imager measures 27cm wide by 38cm high.
